Coming in at second is one that we are pretty excited about here at HAD. The Raspberry Pi has finally launched! For those of you who haven’t been following its progress, this is a small (roughly the size of a credit card) Linux computer that costs only $35 for the better model! We can think of all sorts of things that we would like to use them for but alas, even we can’t get our grubby hands on them quite yet since they are already completely sold out.

In second place is a post about a nice project by [Joel] where he converted an overhead projector into a TV projector by projecting through a LCD TV. He went all-out on this one by using a CNC machine to cut out a special holder for the LCD and the fans necessary to cool it.

Following that is a follow up post about Printrbot, an inexpensive 3D printer which we previously posted about. It was a successful Kickstarter project a couple of months ago and now the design files have been released into the wild. Check it out!

Finally we finish off with a post about how to build a solid-state Tesla coil. It’s presented in an Instructable with 12 easy steps so that you too can feed your high-voltage addiction.

Following that is a post showing how you can overlay video onto an encrypted HDMI signal. The MPAA would probably like to crack [bunnie] over the knuckles with a ruler for this one but he actually isn’t decrypting anything. Instead, he is encrypting the overlay and just replacing the normal video with it.

We like this next one a lot because it not only is a nice hack but it allows you to subtly control what can and cannot happen around you. Specifically, you can jam remote control helicopters with this device. It probably wouldn’t be too hard to pair this up with a TV B Gone to keep people from turning the TV back on once you have wrought your mischief.

Finally, another really neat one for you. In this post, we show [Sprite_tm’s] radio transmitter that is composed out of two button cell batteries, two lengths of wire and an ATtiny processor. It is amazing that this even works but with the right tools, a good hacker can do just about anything.

In case you were asleep at the wheel, here are our top stories of the week.

Our most popular post was one that shows you how to make your own ‘personal assistant’ using Wolfram Alpha, text to speech software, and the phone network. It still won’t get your coffee though. You’ll just have to do that yourself.

When is our government going to get it through their heads that we don’t want the internet to be controlled by a small group of corporations? Probably when the lobbyists stop giving them money by the boat load to do just that… It seems like several times a year a bill comes through that would severely restrict the internet or would at least allow someone to shut down a website without any sort of due process. Luckily, groups like the EFF are paying attention and are well organized for getting the word out there. This post was our stand against the current bills that threaten our internet freedom.
